front, of a piceous hue, the discoidal punctures rather large. Elytra scarcely so long 
as the thorax, closely and finely punctate, and rather densely pubescent ; hind body 
very finely, closely punctate. 
Only a single example has been secured; it is a male, and in the structure of the 
front of the head resembles the same sex of P. mollis, the front of the head being 
curvedly emarginate, and the labrum separated from it by a large membranous space ; 
the anterior tarsi are rather broadly dilated, and the terminal ventral plate exhibits a 
rather broad, but not deep notch.

35. Philonthus quadraticollis. (Tab. X. fig. 16.) 
Robustus, parallelus, nitidus, niger, parce fusco-pubescens ; elytris eneis ; coxis femoribusque testaceis; capite 
quadrato; prothoracis seriebus grosse punctatis; elytris abdomineque parce punctatis. 
Long. 9-12 millim.

The mandibles are elongate, a good deal curved at their apices; the terminal joint of 
the palpi is very elongate and slender. The antenne are scarcely thickened externally, 
the penultimate joints not quite so long as broad. The head is large, broad, and nearly 
square, with four quadrately placed large punctures on each side between the eyes. 
The thorax is a little narrowed behind. The elytra are about as long as the thorax, 
with ascanty, very distinct punctuation, and rigid pubescence. The hind body only 
very sparingly punctate. | 
The male has the head larger, and largely depressed in the middle in front; its 
anterior tarsi are undilated, and there is a slight emargination of the apical ventral 
plate. This is a very distinct species, not closely allied to any other; the Brazilian 
examples are of a more pallid colour, but show no important difference. The figure 
is taken from a male found at Cordova. 
36. Philonthus letipennis. (Tab. X. fig. 17.) 
Parce punctatus, nigerrimus ; elytris cyaneis; scutello fortiter punctato. 
Long. 7-8 millim. 
Hab. Mexico, Misantla (Flohr). 
Mandibles slender, elongate, and acuminate ; last joint of maxillary palpi very long
